Asthma is a condition of lungs that can lead to inflammation or swell ing and soreness of air pathways. [1] Asthma and similar allergic ailments are substantially increasing within an alarming rate globally. Westernized countries and countries switching over to a westernized lifestyle have greater incidence of asthma in comparison with less advanced countries. Though latest scientific studies show the occurrence of asthma is at peak in western world, yet there are no explanations available to date for the same. Scientific studies show that the varying situations as well as the behavioural patterns connected with the so called “westernized” lifestyle have the effect of increase in the frequency of asthmatic attacks amongst general population. For instance, due to upgrading in hygiene and treatments for infectious diseases, it really is hypothesized that diminutive exposure to contagious agents during infancy might lead to the development of asthma and allergies. Accordingly, few studies have publicized that contact with markers linked with contagious and infectious agents like endotoxins, farm animals and pets can reduce the possibility of such ailments. Furthermore, various other attributes of the westernized lifestyle like Obesity and experience allergens have been in connection with the development of such disorders. Additionally, dietary changes that have happened over the periods amongst all age ranges and in special conditions (pregnancy etc.), is the one other significant facets of modern lifestyle which may have contributed to these conditions.

Some of risk factors attributed by present lifestyle and bringing about Asthma are:

- Obesity

- Smoking

- Diet and Nutrition

- Exercise(exercise induced asthma)

- Medications

- Occupational Exposure

- Stress

- Environmental Exposures: Inside and outside Air pollutants; Allergens

[2,3 and 7]


Obesity or excessive weight is amongst the major lifestyle diseases. A great deal of scientific data reveals that Weight problems are a causative factor for Asthma. Your data is collected from adults, adolescents and youngsters worldwide and specify an elevated relative risk of asthma from the obese and overweight and express that Obesity predates Asthma. The mechanical basis of this correlation just isn't yet established. However, as per scientists viewpoint Obesity and Asthma share common etiology like common genetic predisposition, similar results of in utero conditions, or that obesity and asthma are mutually the consequence of certain other predisposing factors such as physical activity or diet.[4]

Moreover, research studies shows that obese patients have an overabundance severe asthma as compared with normal weight individuals etc severity can be due to greater respiratory inflammation, that is certainly, airway obstruction or it can also be due to compact effects of asthma drugs or medications in Obese patients. [5]

Such patients are advised by physicians to check out a strict weight management schedule consisting of daily exercise and morning walk to be able to have a healthier lifestyle.

Latest research on enhanced chance of asthma after the commencement of habitual smoking during upbringing and teenage life corresponds with the substantial data showing that active smoking ends in unpleasant and severe respiratory health effects in adolescents and youngsters after a brief amount of constant smoking. The fact teenagers who smoke constantly have more severe symptoms lower lung function within the first couple of years of commencement has been acknowledged by researchers all over the world. In addition to this, studies have proved that regular or continuous smoking enhances the possibility of asthma and also other respiratory disorders which significant long-term effects of smoking aren't just restricted with those using a history of smoking for several years.

Moreover, recent medical study studies have established that paternal and maternal smoking (pregnant and breast-feeding mothers who're regular smokers) can result in undesired health consequences on new-borns, childrens and teenagers, making their body susceptible to asthma and other severe respiratory tractinfections.

Efficient tobacco control endeavours focusing on the control and protection against smoking in children, teenagers, teenagers, women of childbearing age and women that are pregnant are immediately necessary to prevent the severe installments of asthma in these people.[6]

Nutrition and diet

Scientific studies have established a diet rich in marine efas, peculiarly fish oil, can have valuable effects on inflammatory conditions like asthma.Also, berry eating can lead remarkable improvement in the signs of asthma.Though, the influence of dietary salt lowering of the treatment of asthma is just not yet established by researchers, however it has been concluded that there is significant improvement in pulmonary function having a low-salt diet. [7]

Exercise Induced Asthma

Exercise-induced asthma is described as a state in which smooth muscles in the lungs starts contracting due to physical action. Because of this, breathing becomes hard as well as a person physical performance declines inevitably. Exercise-induced asthma is much more common in athletes who perform rigorous exercises as a part of their daily routine. The most frequent symptoms of Exercise-induced asthma are: wheezing, difficulty in breathing, chest tightness, coughing and problems with prolonged sessions of exercise.

The less frequent symptoms include stomach pain, nausea, lack of ability to exercise in cold, chest congestion/discomfort, frequent colds, dry throat and headache

Proper warm -up or cool-down may prevent or lessen the occurrence of Exercise Induced Asthma.Also, as environmental factors such as cold, dry air, thin air, airborne allergens and food allergens like egg whites, peanuts, almonds or bananas, two hours before exercise can trigger an Allergies, it is highly advisable to perform exercises in finest circumstances or conditions characterised by warm, humid weather; negligible level of pollutants or allergens; plus a moderate altitude. [8]


Substantial evidence of augmented or increased airway resistance is observed in normal individuals and asthamatic patients using medicines like propranolol and aspirin.Similar evidence continues to be seen in Asthmatic patients using Timolol eye drops for glaucoma.

Various other drugs which are seen to provoke Asthma attack are: Cocaine, Dipyridimole, Hydrocortisone, Interleukin-2, Methylphenidate, Nitrofurantoin, Sulfasalazine, Protamine and Vinca alkaloids.

These drugs needs to be avoided as much as possible and should not be taken without prior approval or consultation of Physicians.[9]

Occupational Exposure

Present-day Workplace act as an add on to occupational respiratory diseases like Asthma as a result of inhalation of both organic and inorganic substances. Globally, Asthma is the prime diseases caused due to inhalation of organic agents. [7]

Commonly related occupations and exposures are: car painting (isocyanates), hairdressing (various chemicals), domestic and commercial cleaning(cleaning solutions), medical researchers(latex) and baking(flour dust), amongst many others.[2]

Avoidance of such substances, specifically for people working in industrialized environment is not easy.[7] Thus, private and public sectors should implicate certain health policies, compensative and safety measures for the well being with their laboured employees, contributing to the entire wellness of their companies.


 Stressful life circumstances advances the outward symptoms of asthma. Reports have demonstrated the fact that concomitant parental and private disputes enhances the chance for Asthma at an early age, at the much higher rate in comparison to other risk factors like parental asthma, education and passive smoking.[10].

Moreover, recent clinical findings have enumerated a range of emotional states as probable precursors of asthmatic symptoms. It had been confirmed that distinct affective states like sadness or depression are predominantly related to an exasperation of sign and symptoms in individuals with asthma. Correspondingly, latest many studies have revealed that variant emotional and affective states such as anxiety, anger, and joy are similarly capable of eliciting increases in airway resistance in asthmatics. [11]

Environmental Exposures

Indoor and Outdoor Air Pollutants:

Indoor Air Pollutants, basically indoor allergens, nitrogen dioxide, formaldehyde, chemical toxins, indoor generated particles and co can influence the the respiratory system and can cause or aggravate the outward symptoms of asthma.

Similarly, long-term experience combustion related fine particulate pollution is another significant environmental risk factor for respiratory diseases like asthma.

Once again, relative efforts are required by government and local public generally speaking to combat the inside and outside pollution by adopting living. [7]


Both indoor allergens like mites, some moulds, animal danders and insects and outdoor allergens like pollens and fungal moulds are located to exacerbate the signs and symptoms of asthma as well as other respiratory disorders. Physicians recommend proper adoption of preventive control measures by general public to diminish the harmful affects of allergens on sensitive lungs.[7]


Asthma can be defined as condition of lungs that may lead to inflammation or swelling and soreness of airways. Obesity, Smoking, Diet and Nutrition, Exercise (exercise induced asthma), Medications, Occupational Exposure, Stress and Environmental Exposures: Outdoor and indoor Air pollutants; Allergens are the major risk factors attributed by current modernized lifestyle that happen to be responsible for causing or alleviating the outward symptoms of Asthma. By adopting fitness, consisting of proper diet and resisting to harmful habits of smoking and employ of undesired medications will help in combating the severe signs of Asthma. Furthermore, a prominent role is required by government and private sectors as well as by way of a common man to relieve the detrimental effects of outdoor and indoor air pollution as well as the occupational and emotional stress; on sensitized lungs of an normal human-being.
